This should probably be the same article as #54, unless I'm misinterpreting the title and summary.

Ah I think I should have worded this in a better way.

This issue is for explaining how to run the sample when working with the duality source code.

The other issue is for when users work in their own project and install a sample.

Could probably be explained in the same article though..
